Isomeric Boron−Fluorine Complexes with Donor−Acceptor Architecture:  Strong Solid/Liquid Fluorescence and Large Stokes Shift

Novel isomeric fluorine-boron complexes with donor-acceptor architecture have been efficiently synthesized and well characterized. Significant features, such as strong solid and liquid fluorescence, unusual large Stokes shifts, and lower LUMO levels and higher HOMO levels, are observed in these potential multifunctional molecules.
